Sure. You can engage in post - game content if there is any, like extra boss battles or side quests. Sometimes these can provide more backstory or character development. And of course, you can discuss the story with other fans, sharing your thoughts on what happened in Kingdom Hearts 3D and speculating about future installments.
Well, in the Kingdom Hearts universe, there's no official indication that the characters read fanfiction. But it's an interesting thought. If they did, Sora might be a bit confused at first, since fanfiction can have all sorts of wild interpretations. He'd probably take it in stride though, with his positive and open - minded nature.
We can expect a lot of emotion. Sora is a character full of heart, and Xion has her own emotional baggage. When they meet, it could be a heart - wrenching moment as Xion may reveal her struggles. Sora, being the hero he is, would likely try to comfort her. They might also have a battle of some sort, either against a common enemy or due to some misunderstanding at first.
In fanfiction, when Leon meets Roxas, it could be a moment of confusion. Leon, being a more experienced character, might initially be cautious of Roxas. Roxas, on the other hand, might be curious about Leon. They could start by sizing each other up, perhaps with a bit of posturing. Leon might be trying to figure out if Roxas is a threat to the world he's been trying to protect. And Roxas could be wondering if Leon is an ally or an enemy in his search for his own identity.
No, usually you don't get trophies just for watching the back story. Trophies are typically earned through completing specific in-game tasks or achieving certain goals.
They could have a friendly conversation. Leon might ask Roxas about his connection to Sora. Since Leon knows Sora, he would be interested in any relation Roxas has to him. Roxas could explain his situation, and Leon might be sympathetic. He could offer to help Roxas find out more about his past.
Sure! Sometimes, there could be post-game areas or hidden elements to discover after the main story concludes. It depends on the game's design and developers' intentions.
